From 402b310cb6e523779149139b20f46899a890e963 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Tue, 16 Oct 2007 23:31:09 -0700 Subject: PNP: remove null pointer checks Remove some null pointer checks. Null pointers in these areas indicate programming errors, and I think it's better to oops immediately rather than return an error that is easily ignored.
